(or fill--86) This inventionirelates to adevice adapted to the used to advantagefor transferring dust-from .a.sweeper-bagi-intda receptacle and consistsin :the novel featureshereinafter described and claimed.

An object of such as indicated the invention isto provide means whichmay be enectuallyused for transferring the dust andat the same timepreven lng any of being prov thedust from escapin With this object inView,

-..-c e to which the dust is transferred d with a cover for thecontainer, said cover having an opening.

the device includes a container A collar is provided with sli'iableoverlapping end portions and one end of the collar is fixed to the coverat the opening thereof.

Blades are attached to the collar and have end portions slidable underthe top of the cover.

The collar is adapted to enter the mouth of the sweeper bag and meansare provided for dilating the collar whereby it fits snugly in the mouthof the sweeper bag and the dust cannot escape as it is being transferredfrom the sweeper bag into the receptacle.

In the accompanying drawings: Figure 1 is a vertical sectional view ofthe device.

Figure 2 is a horizontal sectional view out on the line 22 of Figure 1.

Figure 3 is a similar view out on the line 3-3 of Figure 2.

is indicated at 2.

Ihe apparatus consists of a container 3 adapted to receive the bag 2,the said container being provided with a bail handle 4. A cover 5 isadapted to close the upper end of the container and the cover isprovided with lugs 6 adapted to enter the eyes '7 of links 8 which areconnected by means of springs 9 with staples k 10 attached to thecontainer 3. the cover is held in position upon the top of thecontainer.

By this means The cover is provided with a central opening A collarstrip 12 is located in said opening and cent in general circular formand having overlapping ends.

One end of the collar strip -is nxedtothe cover. 5 at the-edge oitheopening, 11 thereof. Qne end of the collarstrip12v is provided at itsinner side with a guide 13 which slidably receives a tongue is providedat the. other of. the collar strip. One endof the collar "strip 12 isprovided with a. slot 15 and finger lugs ldare mounted upon thesaid endof the collar strip at the ends of the slot. A bolt 17 is, carried-bythe other end ofthecollar strip and the said holtpasses throughtheslotrlfi and=,ca r ries a knob .18 over its outer end. 'Aspri-ng19,13. .housedin the knob and bears at one end against the end thereofand at its other end against the nut 20 mounted on the bolt 17. Thespring 19 is under tension with a tendency to hold the end portions ofthe collar strip 12 in frictional contact with each other and also tomake a tight contact in order that dust may not escape between theoverlapping end portions of the collar strip. By placing the edge of theforefinger against one of the lugs lb and the thumb upon the knob 18 andby closing the thumb toward the finger the knob is moved whereby thecollar strip 12 is contracted or dilated as desired.

Blades 21 are provided with upstanding flanges 22. The flanges 22 areattached to the inner surface of the collar strip 12 and the blades 21extend under the top of the cover 5. The edge portions of the adjacentblades overlap each other as best shown in Figure 2 of the drawings. Aspacing ring 23 is attached to the peripheral portion at the top of thecover 5 and at the under side thereof and a plate 24 is attached to saidspacing ring and is provided with an edge portion which extends underthe overlapping blades 21 and serves as a guide and closure for the endportions of the blades. In use, the mouth of the bag 1 is placed aroundthe collar strip 12 and by using the thumb and forefinger upon the knoband one of the lugs 16 as hereinbefore described, the collar strip 12 isdilated or expanded whereby it fits snugly in the mouth of the bag 1.The 1 is then brought to a vertical position and the contents thereofpass down through the collar strip 12 and deposit in the bag 2. Inasmuchas the parts fit snugly against each other, there are apertures throughwhich the dust may escape into the atmospheric air as it is beingtransferred from the bag 1 to the bag 2.

As the lar strip is expanded or contracted, the cverlapp portions of theblades 21 may slide with rela 1 to each other and thus the blades willclose the opening at all times and prevent the escapeinent of dust.

2. A device for transferring dust from a sweep' er bag into areceptacle, comprising .a container for the receptacle, a cover for thecontainer, said cover having an opening, a collar having slidableoverlapping end portions, one of said end portions being fixed to thecover at the opening thereof, blades attached to the collar and havingend portions slidable under the top of the cover,

:the adjacent blades having overlapping en'd portions, said collaradapted to enter'the mouth of the sweeper bag, and means 'for dilatingthe :collar.

3. A device for transferring dust from a sweeper-lbag into areceptacle,comprising a container forthe receptacle, a cover for thecontainer, saidcover having an opening, .a collar having slidable overlapping endportions, one of said end por tions being fixed to the cover at theopening thereof, blades attached to the collar and having end portionsslidable under the .top of the cover,

the adjacent blades having overlapping edge portions, a guide plateattached to the cover and having an edge disposed under the overlappingportions of the blades, said collar adapted to enter the mouth of thesweeping bag, and means for dilating the collar.

4. A device for transferring dust from a sweeper bag into a receptaclecomprising a container for the receptacle, a cover for the container,said cover having an opening, a collar having slidable overlapping endportions, spring means for holding the overlapped end portions of thecollar in contact, one of said end portions being fixed to the cover atthe opening thereof, blades attached to the collar and having endportions slidable underthetop of the cover, said collar adapted to enterthe mouth of the sweeper bag, and means 'f or dilating the collar.

-5. A'device for transferring dust from a sweeper bag into a receptaclecomprising a container for-theleceptacle, a cover for the container,said cover-having an opening, a collar having slidable overlapping'endportions, one end portion of the collar havinga guide and the otherend'portion of the collar having a tongue slidable .in said guide, oneof said-end portions being fixed to the cover at the opening thereof,blades attached to the collar and having end portions slidable under thetop ofnthe cover, said collar adapted to enter the mouth of the sweepingbag, and means for dilating the collar.
